Geller and Spencer have cultivated strategic relationships with a network of like-minded individuals and organizations in the U.S and abroad that enable them to reach broader audiences and expand their activity.Key Domestic Allies· David Yerushalmi, an attorney with a record of anti-Muslim, anti-immigrant and anti-black bigotry, is a close ally of Geller and Spencer, and is one of the driving forces behind efforts to ban or restrict the use of Shariah law in American courts. In addition to being on the board of SIOA, Yerushalmi provides the legal representation for Geller and Spencer in their various lawsuits against public transportation agencies.

· Frank Gaffney, a prominent SIOA board member, is founder of the Center for Security Policy, a neo-conservative think tank that has pioneered the anti-Shariah hysteria by publishing materials regarding the threat of an Islamic takeover of the U.S. In a 2009 Washington Times article, in a reaction to President Obama's endorsement of the proposed Islamic center in New York, Gaffney claimed that "there is mounting evidence that the president not only identifies with Muslims, but actually may still be one himself." In 2010, the Center for Security Policy published the book, Shari'ah: The Threat To America, An Exercise in Competitive Analysis, Report of Team 'B' II, which was co-authored by Yerushalmi. The book repeated Yerushalmi's theories about a vast Shariah conspiracy threatening the U.S.

· James Lafferty is an SIOA board member and chairman and founder of the Virginia Anti-Shariah Taskforce #VAST#, a coalition of anti-Shariah, anti-Muslim people committed to stopping the spread of Shariah in Virginia and across the U.S. Geller has called Lafferty "an early warrior to the fight, a pioneer in activism against Islamic supremacism." Geller has also acknowledged on her blog that Lafferty was one of the first to enter the fight against Islamization in America.

· David Horowitz, founder of the right-wing conservative David Horowitz Freedom Center, provides Geller and Spencer with some financial support, including the sponsorship of Spencer's Jihad Watch blog. In recent years Horowitz has sponsored "Islamofascism Awareness Week," a project on college campuses that promotes anti-Muslim views and features events with anti-Muslim activists.Key International Allies
